Description of the patch
This update for ntp fixes the following issues:
- Update to 4.2.8p11 (bsc#1082210):
* CVE-2016-1549: Sybil vulnerability: ephemeral association
attack. While fixed in ntp-4.2.8p7, there are significant
additional protections for this issue in 4.2.8p11.
* CVE-2018-7182: ctl_getitem(): buffer read overrun
leads to undefined behavior and information leak. (bsc#1083426)
* CVE-2018-7170: Multiple authenticated ephemeral
associations. (bsc#1083424)
* CVE-2018-7184: Interleaved symmetric mode cannot
recover from bad state. (bsc#1083422)
* CVE-2018-7185: Unauthenticated packet can reset
authenticated interleaved association. (bsc#1083420)
* CVE-2018-7183: ntpq:decodearr() can write beyond its
buffer limit.(bsc#1083417)
- Don't use libevent's cached time stamps in sntp. (bsc#1077445)
This update is a reissue of the previous update with LTSS channels included.
